Apple’sLowKeyOSX‘Cabernet’ToLaunchLaterThisYear

Much of the attention over the course of the next few months will focus on iOS 7. However, Apple is also working on a new version of OS X. Code-named “Cabernet,” OS X 10.9 is expected to focus on various “power-user enhancements,” according to 9to5Mac.
Like previous OS X versions, Cabernet will take core features from iOS. However, it “will likely not be an overhauled approach to how the operating system feels and functions.”
According to 9to5Mac:

The new operating system includes major enhancements to the Finder application such as tags and tabbed browsing modes. Those additions are notable as many pro-users have relied on third-party solutions and hacks to enable these features. Additionally, the new operating system will include a new Safari web browser with a redesigned backend for improved page loading, speed, and efficiency…

Most likely, OS X 10.9 will be previewed alongside iOS 7 at the Worldwide Developers Conference in June. Its public release date remains to be seen, although it should be sometime this summer. OS X Mountain Lion was previewed on the Apple website in February 2012, and was officially released in July. OS X Lion was released in July 2011.
WWDC 2013 kicks off on June 10.
